The part was used for my tractor fuel tank as i was having big issues with power loss and everything pointed to sediment etc in the deisel tank and the fuel lines. Fitting the deck plate provided an inspection port and easy ability to clean the tank out saving me hours of work versus removing the tank to clean it. Additional material need was a hole saw, gasket gunk and screws.
Great product and easy to install and can be applied to any tank where access is needed.
